Application filed August 22, 1919, Serial No. 319,155. Renewed September 22, 1921. Serial No. 502,512.

To all whom it may concern Be it known that I, CHAnLns Ltrs'rcAR'rnN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in a Sanitary Bottle Top, of which the following is a full, clear, and exact description.

My invention relates to improvements in sanitary bottle tops, and it consists in the combinations, constructions and arrangements herein described and claimed.

An object of my invention is to provide a metal top for use with milk bottles, and which is provided with a resilient airtight closure.

A further object of my invention is to provide a device which has an airtight closure, and which may be opened by the hand that grasps the bottle, thus allowing one to open and pour with one hand into a receptacle, such as a cup, held by the other.

A further object/of my invention is to provide a metal top having a resilient closure with means for removing the ordinary paper or pasteboard cover which milk dealers apply when distributing the mllk 1n bottles.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which I Figure 1 is a plan view of my improved bottle top or cap,

Figure 2 is a section through the improved top and the upper portion of a bottle to which the top is applied,

Figure 8 is a section along the line 3-3 of Figure 2, and

Figure 1 is a section through the device showing the manner of removing the pasteboard closure.

In carrying out my invention, I make use of a circular metal disk 1 whose outer edges curve to conform with the rounded upper end of the bottle 2. The disk 1 has a centrally depressed portion 3, which is less in diameter than the mouth of the bottle. This depressed portion forms a backing for the resilient closure 1 which may be in form of a rubber washer or any suitable resilient member which fits snugly against the shoulder 5 of the bottle. This closure or washer is held between the depressed portion 3 and a circular plate 6.

The latter bears a prong 7 which may be made integral with the plate 6. The plate 6, the washer t and the central portion 3 of the plate 1 may be held together in any suitable manner, as by means of a rivet 8.

The plate 1 has an extension 9 at one side thereof which is preferably integral with the plate and which is bent downwardly as shown in Figure 2. This extension rests against the curved upper portion of the bottle 2 when the top or cap is in its closed position.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood.

As stated above, the milk is delivered in bottles having a pasteboard stopper or closure. By grasping the disk 1, the prong 7 may be thrust through this paper cap, as shown in Figure 4-. Now, by placing the plate on the upper edge of the bottle and raising the handle or extension 9, the paper stopper may be readily removed without spilling the milk. The pasteboard disk may then be removed from the prong and the metal top may be replaced. It will then occupy the position shown in Figure 2. In this figure it will be seen that the closure 4 fits snugly against the shoulder 5, thus clos ing the bottle hermetically. The bottle may be grasped with one hand, with the finger on extension 9, and by pressing the finger toward the bottle neck, the cap will be pried up against the tendency of the'resilient closure to cling to the shoulder 55, on account of its frictional engagement therewith. The milk may be poured out with the same hand that opens the bottle. When the top is replaced, the resilient member 1 is forced down into its closing position. It will be observed that there is no chance for insects to get into the bottle, since the metal edges closely hug the outer rounded edges of the bottle. Furthermore, no germs can get into the milk, while the bottle is closed with this sanitary cover, which, while hermetically sealed, makes the milk always germ proof and the cover sanitary. The resilient closure 4 is designed to retain the bottle top in'position, even if it should be knocked over. Notwithstanding the fact that this closure fits tight, the provision of the extension 9 affords a lever, by means of which the closure may be forced out of position to open the bottle and to permit the pouring out of the contents thereof, as stated.

am aware that this device may be changed in unessential particulars and yet retain the main principles of the invention, and I, therefore, desire to include all such modifications as fairly fallwithin the spirit and the scope of the invention.

I claim:

1. A bottle top or cap comprising a circular metal disk having its outer edges contween said centrally disposed portion and said second named disk, and an extension from one edge of said first named disk, said extension having a. portion bearing on the rounded upper edge of the bottle when the top is in its closed position.

2. A. bottle top or cap comprising a circular metal disk having its edges bent to: conform. with the curvature of the upper edge of the bottle, said disk having a centrally depressed portion, a resilient closure secured to the centrally depressed portion, said resilient closure being greater in diameter than the mouth of the bottle and being arranged to engage the narrow walls of the mouth of the bottle to hermetically seal the same, and an extension carriedby said first named disk at one edge thereof, said exten sion serving as a lever forprying loose the resilient closure.
